iFUIEL-SAVING DEVICE FOR LOCOMOTIVES.

SPECIFICATION forming part 0f LetteIS Patent No. 595,321, dated December 14, 1897.

Application filed January12, 1897. Serial No. 619,011. (No model.)

To a/ZZ whom it may concern:

Be it known that I, CHARLES B. LORD, residing at Astoria Station, Long Island City, in the county of Queens and State of New York, have invented a new and useful Fuel- Saving Device for Locomotives, of which the following is a specification.

This invention relates generally to locomotives, and more particularly to an attachment whereby an even draft is maintained, economizing greatly in the use' of fuel.

Heretofore in locomotives as generally constructed the draft has been created by the exhaust-nozzle which leads from the steamcylinders. This plan, however, has been very wasteful to the fuel, inasmuch as the blast from the exhaust-nozzle draws the fuel from the fire-box and ejects the same through the smoke-stack before it has been subjected to the proper combustion, and it is therefore impossible to obtain all of the heat from any given quantity of fuel. Furthermore, the use of wire-netting, petticoat-pipes, rbc., has been necessary in order to prevent the exhaust-nozzle ejecting sparks from the smokestack, and all of these devices, however, seem to more or less interfere with the draft.

The object, therefore, of my invention is to avoid all of these objections and create a draft by a blower only, which is operated by the surplus steam from the boiler-head; and another object of the invention is to carry the exhaust-steam continuously from the saddle to the top of stack in order to reduce the noise from the exhaust and the back pressure upon the pistons to a minimum.

Vith these objects in view my invention consists, essentially, in continuing the eX- haust-pipe to the end of the smoke-stack upon either the inside or the outside and arranging ablower-nozzle directly below the center of the stack, whereby an even and steady draft is obtained by a moderate use of the blower while using steam through the cylinders.

The invention consists also in providing a detachable blower which can be quickly and easily attached or detached as desired.

The invention consists also in providing an expansion-chamber directly above the saddle,

whereby the back pressure upon the pistons is reduced to a minimum.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a view showing the practical application of my invention. Fig. 2 is a detail view showing the manner of arranging the blower-pipe in connection with the exhaust-pipe, said exhaust-pipe being arranged at one side of the stack and provided with an expansion-chamber. Fig. 3 is a detail view showing the manner of arranging the blower in connection with the eXhaust-pipe,arranged centrally with the stack and provided with an expansion-chamber. Fig. 4 is a detail scctional view showing the manner of connecting the blower-nozzle to the steam-pipe. Fig. 5 is a detail perspective View of the blower. Fig. 6 is a detail view showing a modified form of exhaust-pipe and stack. Fig. 7 is a transverse section on the line 7 7 of Fig. G.

In carrying out my invention I employ a blower A,which consists, essentially, of a pipe bent in the form of a triangle and provided with a series of jet-nozzles A upon the upper side thereof. The lower portion of the blower is screw-threaded, as shown at B, and has a collar C fastened thereon, said collar having notches or recesses D produced therein at deiinite points. The pipe E, leading from the boiler-head or steam-dome, is also threaded at its upper end to receive the sleeve F, the upper interior portion of the said sleeve being smooth in order to permit the collar C slipping therein, and attached to the exterior of the sleeve F are the springs G, constructed with inwardly-projecting locking-pins II, which pass through openings I in the sleeve F and engage the recesses or notches D, produced in the collar C, and thereby securely connect the blower with the supply-pipe. In order to effect such connection, it is only necessary to insert the lower end of the blower, provided with a collar C, and in order to detach the blower it is only necessary to press the springs outwardly, which operation withdraws the locking-pin II, and the blower can then be lifted from the sleeve F. It will of course be understood that the collar C can be dispensed with, if desired, and the lower portion of the blower provided with notches or recesses to receive the locking-pins H. It will also be understood that the end of the pipe E can also be provided with the springs G and thereby i avoid the necessity for the sleeve F.

K indicates the exhaust-pipe, which leads from the cylinders and extends enti-rely through the smoke box or chamber and through the. smoke-stack to the topy thereof, said exhaust-pipe being arranged at one side of the stack, as shown at Fig. 2, or centerthereof, as shown in Fig. 3. prefer to construct the exhaust-pipe with anl expansion-chamber L, which permits the eX- haust-st'eam toexpand as it escapes audit-hereby reduce the back pressure upon the-pistons to a minimum.

The pipe E is secured or held in place by means of a bracket'M, which is attachedy to the exhaust-pipe K, as most clearly shown in; Figs. l, 2, and 3.

lt will be noted that the blower is arranged directly beneath the center of the smokestack in order tocreate the proper draft, and in case the exhaust-pipe is arranged centrally of the smoke-stack, as shownV in Fig. 3, the member or nozzle portion of the blower is curved to embrace the said pipe, as clearly shown in Fig. 3. The essential features, however, remain the same in all ofv theconstructions.

The operation of. my device is clear to every one skilledV in the art to which it pertains, as it will be seen that a uniform draft will be maintained at all times by the usey of thev blower supplied directly from the boiler-head,

and it will also be noted that the noise of exhaust and the back pressure upony the pistons will be reduced to a. minimum.

In either case I Furthermore, the Wire-netting and petticoat-pipes are entirely dispensed with, as Well as sparkarresting devices of all constructions.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a locomotive, an exhaust-pipe extending from the saddle through the smoke-stack and to the top of the stack and enlarged, Within the smoke-box, to form an expansionchamber, in combination with a live-steam blower partly around the, exhaust-pipe and supported from said exhaust-pipe, all substantially as set forth.

2. In a locomotive, in combination, the boiler-head, a draft-nozzle located below the stack, a pipe leading from the boiler tothe nozzle, and ai spring-operated detachable connection between the pipe andnozzle, all substantially as set forth.

3.I In a locomotive, the combination with the pipe leading from the boiler-head, havingy holes through its sides near the-end, the

` blower-pipe having holes or notches registertially as show-n and described.
